Abstract

The invention relates to a pipe-withdrawing device for replacing pipes 8 of domestic supply-line networks. In order to reduce the number of operational failures to a minimum, a positive transmission of the withdrawal forces to the pipe 8 is provided instead of the hitherto conventional non-positive transmission of the withdrawal forces. For this purpose, a pressure plate 5 is mounted on the working cylinders 4. Its abutment is a clamping block 9 which can be secured to the pipe 8. <IMAGE>
